For sale is a used 1980 Marshall JMP 2204 50 Watt Tube Guitar Head. If you are looking at this listing, than you already know this is one of the greatest amps that Marshall has ever made. Hands down my favorite, as it delivers that raw and rude tone you would expect from a late 80's era Marshall. This amp has been played and has normal wear that would expect from a 37 year old amp. There is wear to the tolex, a couple of the knobs where replaced, and the pilot light to the power switch is not working. The amp still turns on perfect. With the exception to the tubes, some knobs, and the Marshall logo, and filter caps, everything is original on the head. The tubes have plenty of life left in them.
